Current River Generating Station (0.5 MW) - Thunder Bay: Current River

On January 1, 2015, the Ontario Power Authority merged with the Independent Electricity System Operator to create a new organization that combines the OPA and IESO mandates.

The Current River Hydro Partnership is a partnership between Whiteside Power & Light (80% ownership) and 1188750 Ontario Limited (20% ownership).

The Current River Generating Station is a single-unit hydroelectric station located on Current River in Thunder Bay. The station was commissioned in January 1987, and has an installed capacity of 0.5 MW at a head of 34 feet.

The generating site is a run of the river site. A concrete spillway of a few hundred feet is equipped with stop logs to control the water level in Boulevard Lake. The lake’s primary function is for recreational use with power generation being a secondary function. The dam is owned, operated and maintained by the City of Thunder Bay. The penstock coming from the concrete section of the dam is a fibreglass pipe 600 feet in length and 4 feet in diameter. Two manual knife gate valves at the dam are used to isolate the penstock. The penstock is completely buried and out of sight. A butterfly valve is located about 20 feet upstream of the turbine generator, and is hydraulically driven and controls the flow of water to the turbine. The station uses 3.9 CMS of water for operation.

The lease agreement with the City limits the operation of the plant to 10 months with the project not operating during the months of July and August each year to allow water to spill over the dam for aesthetic reasons.

This hydroelectric generating station generates approximately 1,750 MWh of renewable energy per year.
